Hi all,
I hope someone can give me a bit of advice. I have had my PC for roughly 3 and half years now. During that time the PC has been watercooled. With one loop cooling the cpu and gpu with a quad feser radiator.
Temps for the cpu and gpu cores are really good. But around a year ago I started getting issues with the screen going black and my monitor saying "no dvi signal" and then would proceed to reboot my pc. I tried all sorts to stop it from happening but the only thing that seemed to work was disabling my 2nd core on my gpu (4870x2). So I thought that my 2nd core was faulty and maybe on it's way out. Around 3 weeks ago the issue started to come back even with the core disabled as my wife was just browsing the net one night when the screen went black, no dvi signal. It would then happen every time I tried to boot up, get to just before the desktop screen and go black again.
I got really frustrated at this point as the gpu has never been overclocked and has been virtually under water from day one. I decided to take all of my ram out, unplug cables, unscrew my gpu as much as the tubes would allow me too and put it all back in. The gpu had quite a bit of room to go back into the pci-e slot so I thought that maybe over time with the weight of the tubes/water it's pulled the gpu away from the pci-e slot ever so slightly which may have been causing me the crashing issues. I did all this and it's been fine for the last two weeks. Crossfire was working again and it was like having my old PC back. I even bought Counter Strike: Global Offensive to celebrate!
No overclock on my CPU and temps all looking good. When gaming 56 for cpu and 43 for gpu. Anyway, it happened again last night. Gaming on CS:GO then black screen, real temp alarm goes off and reboots. I then go back into CS:GO and within 5 mins same thing happens again.
There's no way the cores are overheating with the temps I've mentioned above and I have real temp alarm set to go off at 65 for cpu and 50 for gpu.
I loaded CS:GO for a third time but before doing so I ran AIDA64 to monitor all temps. Kept flicking between that and the game and noticed that the VRM Temp for 2nd core was rising quickly and it got to 78 degrees but I was still gaming ok but I'm guessing that If I'd of gamed a little longer I'd of got the black screen again. Does this sound too high for the VRM? It was 15 degrees hotter than the VRM on core 1.
Sound like a gpu issue or something else perhaps? I appreciate this is a long post and not written very well but if anyone could offer help I would really appreciate it. I really don't want to have to replace anything as its such a chore when you have it watercooled. Plus, my gpu handles CS:GO maxed out at 1920 x 1200 with ease and it's the only game I play.
Many thanks,
RoEy
